“It’s a shame this generation that is around now, these kids, feel it’s fine to block my First Amendment speech — including almost setting my house on fire. To them, that makes sense,” Pirozzolo griped to The Post.

Under New York’s Penal Law, an offense can be prosecuted as a hate crime only if it targets a victim’s “race, color, national origin, ancestry, gender, religion, religious practice, age, disability or sexual orientation.”

First, the left rioted at Trump rallies, now they’re destroying signs. What’s next?
